Abstract

The invention discloses a method for determining the content of monomethylamine and monoethylamine in cigarette sidestream smoke by ion chromatography, which comprises the following steps: capturing monomethylamine and monoethylamine, processing cigarette smoke samples, and stock solution And the preparation of the standard working solution, the supernatant was analyzed by ion chromatography. The present invention realizes the accurate determination of monomethylamine and monoethylamine in cigarette sidestream smoke, overcomes the derivatization-gas chromatography used in the determination of monomethylamine and monoethylamine in cigarette mainstream smoke in the prior art The method has the disadvantages of cumbersome operation, time-consuming and laborious, and difficult to quantify accurately. It has the advantages of simple pretreatment, accuracy, high sensitivity, and good repeatability. According to the distribution of monomethylamine and monoethylamine in gas phase and particle phase in sidestream smoke, it is theoretically more reasonable to separate gas phase and particle phase for detection, and it is convenient to grasp the distribution of monomethylamine and monoethylamine in gas phase and particle phase. Distribution in the gas and particle phases.

Description

technical field [0001] The invention belongs to the technical field of physical and chemical testing, and in particular relates to the determination of organic amines in cigarette sidestream smoke. Background technique [0002] During the burning process of tobacco, the thermal degradation of nicotine or other alkaloids may generate monomethylamine and monoethylamine. Monomethylamine and monoethylamine have a strong stench and are harmful to the skin, eyes, upper respiratory tract and lungs. Strong stimulating and corrosive effects. When poisoned, the central nervous system is damaged, which can lead to bronchitis, bronchitis, pneumonia, and even pulmonary edema. my country stipulates that the allowable concentration of monomethylamine in the air is 5mg / m 3 . The presence of monomethylamine and monoethylamine in cigarette smoke not only has a great impact on the taste of cigarettes, but also has a negative impact on the surrounding environment in sidestream smoke.
